Please be assured that I am VERY familiar with the rules of time travel as explained by Kyle Reese in the first movie. When Cromartie’s head goes through the time bubble, THERE IS FLESH ON IT. If you can’t see it, that’s because a) it’s burning off very quickly and b) certain people don’t like it when we show burning flesh, cyborg or not.
(Historical note: The first person to ask me this head/bubble question was Jared in Props--a year ago while we were shooting the pilot.)
